[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-11This invention provides a technical solution: a modular combined karaoke speaker system, including a speaker body 1. An adjustable component 2 for karaoke selection is located near the center of the top of the speaker body 1. A movable component 3 is located near the edge of the top of the speaker body 1. The adjustable component 2 includes a fixed plate 201. A turntable 202 is rotatably connected to the inner wall of the fixed plate 201 at its center. Multiple evenly arranged first springs 203 are arranged near the edge of one side of the outer surface of the fixed plate 201. One end of each of the multiple first springs 203 is fixedly connected to a first ball 204. Multiple evenly arranged fixed cylinders 205 are fixedly connected near the edge of one side of the outer surface of the fixed plate 201. Multiple evenly arranged... The first circular groove 206, two first fixing plates 207 are fixedly connected to the other outer surface of the turntable 202, a first fixing shaft 208 is fixedly connected between the outer surfaces of the two first fixing plates 207, a rotating plate 209 is rotatably connected to the outer surface of the first fixing shaft 208, and first meshing teeth 210 are fixedly connected to both sides of the outer surface of the rotating plate 209. Speakers 4 are electrically connected to both inner walls of the speaker body 1. The other outer surface of the fixing plate 201 is fixedly connected to the top of the speaker body 1 near the center. The other ends of multiple first springs 203 are fixedly connected to one outer surface of the fixing plate 201. The multiple first springs 203 are respectively located inside multiple fixing cylinders 205. The outer surfaces of multiple first spheres 204 are respectively connected to multiple first... The outer surface of a circular groove 206 is in contact with the outer surface of the first fixed shaft 208, which is slidably connected to two second meshing teeth 211. The outer surfaces of the two first meshing teeth 210 respectively mesh with the outer surfaces of the two second meshing teeth 211. A second spring 212 is provided on the outer surface of each of the two second meshing teeth 211. One end of each second spring 212 is fixedly connected to the outer surface of the two second meshing teeth 211. The other end of one second spring 212 is fixedly connected to the outer surface of one of the first fixed plates 207, and the other end of the other second spring 212 is fixedly connected to one side of the outer surface of the rotating plate 209. A connecting plate 213 is fixedly connected between the outer surfaces of the two second meshing teeth 211. The outer surface of the connecting plate 213 is fixed. A movable handle 214 is connected to the rotating plate 209. A second fixed shaft 215 is fixedly embedded in the inner wall of the rotating plate 209 near one edge. Multiple evenly arranged second circular grooves 216 are formed on the outer surface of the second fixed shaft 215 near both ends. Second fixed plates 217 are rotatably connected to the outer surface of the second fixed shaft 215 near both ends. Multiple evenly arranged third springs 218 are arranged on the inner walls of both second fixed plates 217. The multiple third springs 218 are divided into two groups. One end of each group of third springs 218 is fixedly connected to the inner wall of the two second fixed plates 217, and the other end of each group of third springs 218 is fixedly connected to a second sphere 219. The outer surfaces of the multiple second spheres 219 are respectively in contact with the outer surfaces of the multiple second circular grooves 216.A control panel 220 is fixedly connected between the outer surfaces of the two second fixing plates 217.

[0023] In this embodiment, during the use of the modular karaoke speaker, the operator first needs to push the cover plate 313 until it is no longer on top of the speaker body 1. At this time, the operator holds the moving handle 214 and pulls it away from the rotating plate 209, causing the connecting plate 213 and the second meshing teeth 211 on both sides to slide along the first fixed axis 208. At this time, the second meshing teeth 211 compress the second spring 212 and disengage from the engagement state with the first meshing teeth 210 on both sides of the rotating plate 209. While holding the moving handle 214, the rotating plate 209 is flipped around the first fixed axis 208 to the target tilt angle. Then, the moving handle 214 is released, and the second spring 212 resets, pushing the second meshing teeth 211 to re-engage with the first meshing teeth 210. The first meshing tooth 210 engages, fixing the vertical rotation angle. Vertical rotation adjustment is achieved through the locking mechanism of the second meshing tooth 211 engaging with the first meshing tooth 210 and the structure of the second spring 212. The meshing of the tooth surfaces of the first meshing tooth 210 and the second meshing tooth 211 precisely fixes the rotation angle, preventing the control panel 220 from rotating on its own during use. The elasticity of the second spring 212 ensures the meshing teeth remain tightly engaged. Simultaneously, pulling the moving handle 214 releases the lock. The operator holds the edge of the control panel 220 and applies a rotational force horizontally, causing the control panel 220 to rotate and move the second fixed plate 217. The second fixed plate 217 then rotates and moves the rotating plate 209. At this time, the outer surface of the second rotating plate 209... The outer surface of the first meshing tooth 210 meshes with the outer surface of the second meshing tooth 211. When the rotating plate 209 rotates, it drives the first fixed shaft 208 to rotate, thereby driving the first fixed plate 207 to rotate. The first fixed plate 207 drives the turntable 202 to rotate on the inner wall of the fixed plate 201. During the rotation, the first circular groove 206 on the edge of the turntable 202 squeezes the first ball 204 on one side of the fixed plate 201, causing the first ball 204 to compress the first spring 203 in the fixed cylinder 205 and disengage from the current first circular groove 206. When the target horizontal angle is reached, the first spring 203 resets and pushes the first ball 204 to re-embed into the corresponding position of the first circular groove 206, thereby fixing the horizontal angle between the turntable 202 and the rotating plate 209. Spring 203 provides continuous elastic force to keep the first ball 204 always in contact with the turntable 202. Angle adjustment and fixation are achieved by switching the ball between different circular grooves. Multiple evenly arranged first circular grooves 206 can meet the needs of multiple horizontal angles and adapt to the operation field of vision in different usage scenarios. When it is necessary to fine-tune the small angle of the control panel 220 to adapt to the operation gestures of users of different heights, the staff can directly turn the control panel 220 so that it rotates around the second fixed axis 215 through the second fixed plates 217 on both sides. During the rotation, the second circular groove 216 on the second fixed axis 215 squeezes the second ball 219 on the inner wall of the second fixed plate 217, so that the second ball 219 compresses the third spring 218 and disengages from the current second circular groove 216.After fine-tuning to the appropriate angle, the third spring 218 resets and pushes the second ball 219 into the corresponding second circular groove 216, completing the small-angle fixation of the control panel 220. Compared with the first spring 203 and the first ball 204 for horizontal adjustment, the third spring 218 has less elasticity and the second circular groove 216 has a closer spacing, which can achieve more precise angle adjustment, adapt to the hand operation habits of different users, and improve the comfort of song selection operation. This device sets up an adjustable component 2. Through the three-layer adjustment structure of the adjustable component 2, the fixed plate 201 and the turntable 202 cooperate to realize the 360-degree horizontal rotation of the control panel 220. The first meshing tooth 210 and the second meshing tooth 211 cooperate to realize the vertical flip angle locking of the control panel 220. The second fixed shaft 215 and the second ball 219 cooperate to realize the small-angle fine adjustment of the control panel 220. The three-layer adjustment covers multi-dimensional usage needs, adapts to the operating habits of different scenarios and people, and solves the problem that existing karaoke speaker all-in-one machines usually only support single-dimensional adjustment, which requires some users to bend over, tilt their heads back, and turn to the side, resulting in extremely low comfort. ;

[0024] like Figure 1-11 As shown, the movable component 3 includes two base plates 301. The outer surfaces of the two base plates 301 are fixedly connected to the opposite outer surfaces of the speaker body 1. A first rotating shaft 302 is movably embedded in the inner wall of each base plate 301 near one edge. A first pivot plate 303 is fixedly sleeved on the outer surface of each of the two first rotating shafts 302 near one end. A fourth spring 304 is provided on the outer surface of each of the two first pivot plates 303. A second rotating shaft 305 is movably embedded in the inner wall of each base plate 301 near the other edge. A connecting frame 306 is fixedly sleeved on the outer surface of each of the two second rotating shafts 305. A third rotating shaft 307 is movably embedded in the inner wall of each of the two connecting frames 306 near one edge. A second pivot plate 308 is fixedly sleeved on the outer surface of each of the two third rotating shafts 307. One end of each of the two fourth springs 304 is fixedly connected to the outer surface of each of the two first pivot plates 303. The other end of 4 is fixedly connected to the outer surface of the two second pivot plates 308 respectively. Four third fixing plates 309 are fixedly connected to the outer surface of one side of the speaker body 1 near the top. Each pair of the four third fixing plates 309 is a group. A third fixing shaft 310 is fixedly embedded between the inner walls of the two groups of third fixing plates 309. A slide rail 311 is movably fitted on the outer surface of the two third fixing shafts 310. A fourth fixing shaft 315 is fixedly embedded on the inner wall of the two connecting brackets 306 near the other edge. A fourth fixing plate 314 is movably fitted on the outer surface of the two fourth fixing shafts 315. A cover plate 313 is fixedly connected between the outer surfaces of the two fourth fixing plates 314. Two sliders 312 are fixedly connected to the outer surface of one side of the two cover plates 313. The outer surfaces of the two sliders 312 are slidably connected to the inner walls of the two slide rails 311 respectively. A storage component 5 is provided inside the speaker body 1.

[0025] In this embodiment, when the modular karaoke speaker is in use, the outer surface of the cover plate 313 is in contact with the outer surface of the speaker body 1. When the operator pushes the cover plate 313 along the side of the speaker body 1, the cover plate 313 slides along the slide rail 311 on the third fixed shaft 310 between the third fixed plates 309 via the sliders 312 fixed on both sides. As the cover plate 313 slides, it drives the fourth fixed shaft 315 through the fourth fixed plate 314, thereby pulling the connecting frame 306 around the base plate 301. The second rotating shaft 305, which is dynamically engaged, rotates. The other end of the connecting frame 306 drives the second pivot plate 308 to rotate via the third rotating shaft 307. At the same time, the second pivot plate 308 pulls the first pivot plate 303 around the first rotating shaft 302, which is dynamically engaged with the base plate 301, via the fourth spring 304. This continuously pushes the cover plate 313 until the slider 312 slides to the end of the slide rail 311. Simultaneously, as the slider 312 slides along the inner wall of the slide rail 311 on its outer surface, the inner wall of the slide rail 311 will slide along the outer surface of the third fixed shaft 310. The cover plate 313 rotates until it is no longer located on top of the speaker body 1. The sliding displacement of the cover plate 313 is converted into the rotation of the first pivot plate 303 and the second pivot plate 308 through the fourth fixed shaft 315 and the connecting frame 306. The fourth spring 304 plays a reset and buffering role, ensuring that the first pivot plate 303 and the second pivot plate 308 unfold smoothly and avoid damage to the components due to collision. Finally, the unfolding and retraction control of the moving structure is realized. This device sets a moving component 3. Pushing the cover plate 313 can drive the slider 312 to slide and the connecting frame 306 to rotate and unfold. At this time, the control panel 220 can be adjusted. When the modular combination karaoke speaker is not in use, pushing the cover plate 313 can retract the moving component. The cover plate 313 re-fits the speaker body 1. At this time, the control panel 220 is located between the speaker body 1 and the cover plate 313, which can effectively avoid damage to the control panel 220 caused by dust, liquid splashes, accidental collisions and external factors, and significantly extend the service life of the control panel 220 and its internal components.

[0026] like Figure 1-11 As shown, the storage component 5 includes a drawer 501. The outer surface of the drawer 501 is slidably connected to the inner wall of one side of the speaker body 1. Two microphones 502 are placed inside the drawer 501. A first magnet 503 is fixedly embedded on the outer surface of the drawer 501 near the two side edges. Two second magnets 504 are fixedly embedded on the outer surface of one side of the speaker body 1.

[0027] In this embodiment, when the modular karaoke speaker is in use, the operator can pull the drawer 501 of the storage component 5 outwards, overcoming the attraction between the first magnets 503 on both sides of the drawer 501 and the second magnets 504 on the side of the speaker body 1. After fully pulling out the drawer 501, the operator can remove the two microphones 502 placed inside. Then, the operator pushes the drawer 501 back onto the sliding track on the inner wall of the speaker body 1 until the first magnets 503 and the second magnets 504 re-attach and adhere, thus completing the removal of the microphones 502 and fixing them to the drawer 501. The magnetic attraction of the 4-pin drawer prevents the drawer 501 from accidentally sliding out during device movement and use, ensuring the safe storage of the microphone 502. Simultaneously, the sliding structure reduces the operational resistance when opening and closing the drawer 501. This device, through the storage component 5, with its independent drawer 501 and magnetic fixing structure, provides an independent storage space for the microphone 502, preventing exposure and contamination. The first magnet 503 and the second magnet 504 are attracted and fixed, preventing the drawer 501 from sliding out when the device is moved. Simply pulling and pushing the drawer 501 back completes the retrieval and storage of the microphone 502, making operation simple and efficient.

[0028] The usage and working principle of this device are as follows: When the modular karaoke speaker is in use, the outer surface of the cover plate 313 is in contact with the outer surface of the speaker body 1. The operator pushes the cover plate 313 along the side of the speaker body 1. At this time, the cover plate 313 slides along the slide rail 311 on the third fixed shaft 310 between the third fixed plates 309 via the sliders 312 fixed on both sides. As the cover plate 313 slides, it drives the fourth fixed shaft 315 through the fourth fixed plate 314, which in turn pulls the connecting frame 306 to rotate around the second rotating shaft 305 that is movably fitted with the base plate 301. The other end of the connecting frame 306 drives the second pivot plate 308 to rotate through the third rotating shaft 307. At the same time, the second pivot plate 308 is driven by the fourth spring. 304 pulls the first pivot plate 303 to rotate around the first rotating shaft 302 that is movably engaged with the base plate 301, continuously pushing the cover plate 313 until the slider 312 slides to the end of the slide rail 311. At the same time, as the outer surface of the slider 312 slides along the inner wall of the slide rail 311, the inner wall of the slide rail 311 will rotate along the outer surface of the third fixed shaft 310 until the cover plate 313 is no longer at the top of the speaker body 1. At this time, the operator pulls the drawer 501 of the storage component 5 outward, overcoming the attraction force of the first magnets 503 on both sides of the drawer 501 and the second magnets 504 on the side of the speaker body 1, and pulls the drawer 501 out completely. Then, the two microphones 502 placed inside are taken out, and the drawer 501 is pushed back into the speaker body 1. The microphone 502 is retrieved from the drawer 501 and secured to the sliding track of the wall until the first magnet 503 and the second magnet 504 re-attach and adhere. At this point, the operator holds the moving handle 214 and pulls it away from the rotating plate 209, causing the connecting plate 213 and the second meshing teeth 211 on both sides to slide along the first fixed axis 208. At this time, the second meshing teeth 211 compress the second spring 212 and disengage from the engagement state with the first meshing teeth 210 on both sides of the rotating plate 209. While holding the moving handle 214, the rotating plate 209 is rotated around the first fixed axis 208 to the target tilt angle. Then, the moving handle 214 is released, and the second spring 212 returns to its original position, pushing the second meshing teeth 211 to re-engage with the first meshing teeth 210. With the engagement complete and the vertical flip angle fixed, the operator holds the edge of the control panel 220 and applies a rotational force horizontally. This causes the control panel 220 to rotate and move the second fixed plate 217, which in turn causes the rotating plate 209 to rotate and move. At this time, the outer surfaces of the first meshing teeth 210 and the second meshing teeth 211 on the outer surface of the second rotating plate 209 mesh. When the rotating plate 209 rotates, it drives the first fixed shaft 208 to rotate, which in turn drives the first fixed plate 207 to rotate. The first fixed plate 207 then drives the turntable 202 to rotate on the inner wall of the fixed plate 201. During the rotation, the first circular groove 206 on the edge of the turntable 202 presses against the first sphere 204 on one side of the fixed plate 201.The first ball 204 compresses the first spring 203 inside the fixed cylinder 205 and disengages from the current first circular groove 206. When rotated to the target horizontal angle, the first spring 203 resets and pushes the first ball 204 back into the corresponding position of the first circular groove 206, thus fixing the horizontal angle between the turntable 202 and the rotating plate 209. When a small angle adjustment of the control panel 220 is needed to accommodate the operating gestures of users of different heights, the operator directly moves the control panel 220, causing it to rotate around the second fixed shaft 215 via the second fixed plates 217 on both sides. During the rotation, the second circular groove 216 on the second fixed shaft 215 presses the second ball 219 on the inner wall of the second fixed plate 217, causing the second ball 219 to compress the third spring 218 and disengage from the current second circular groove 216. After fine-tuning to the appropriate angle, the third spring 218 resets and pushes the second ball 219 into the corresponding second circular groove 216, completing the small angle fixation of the control panel 220.
